Intel Galileo Vs. Intel Edison?

The Internet of Things has been a recent interest of mine and I'm yet to discover all its nuances.

But even after researching both of these Intel boards on the internet, I'm still confused as to how the Intel Galileo and the Intel Edison differ from each other. Like I really want to understand their difference in terms of which should be bought or used for what purpose in correspondence to their respective specifications.

Hence, for Bluetooth or a faster WiFi, the Intel Edison should be your go-to board. Also, it has a higher processing speed with a more powerful CPU and RAM. Plus, it comes with more flexibility as you can use it with Arduino board while prototyping and even with smaller breakout board while deploying according to the requirement of your applications. So, Intel Edison is definitely the better board in terms of their overall features, which is quite understandable as it is a product of an extra year of research and technological advancements by Intel.
